Help with error 1802

I am bringing in a 60Hz 5v p-p sine wave in from a parent VI.  I am using the limit tester to make sure the signal is there (testing for greater than +-1v).  I keep getting error 1802. It says I have different dt values for the waveforms.

 

I have looked on the boards and don't see a solution that applies to this problem.  The VI is attached.  Any help would be appreciated.

Did you look at this article?  http://digital.ni.com/public.nsf/allkb/C41966093C3D030F86256FF8007F8BF5

 

The dt of your waveform should match the dx of the upper/lower limits.

Yes I did, but those solutions deal with two signals that need to be synced together.  My problem is that I have one signal coming from a source through a limit tester.  I'm not quite sure what I need to sync the limit tester to.

Here's the VI so far.

Did you make sure that the dt of your waveform matches the dx of the upper/lower limits?  Please post your VI

It doesn't look like you have the upper and lower limits wired.
